IMPROVEMENT IN VEHlCLE-SPRINGS.

Specification forming part of Letters Patent N0. 212,542, fiated February 25, 1879 application filed September 21, 1878.

T0 all whom z't may concern:

Bei1; known that I, J OSEPH H. DENIGER, 0f the eity of Bridgeport, county of Fairfield, State of Oonneeticut, have invented zu new zmd useful Improvementin Wagon-Springs, 0f whieh the following is a specification:

My invent-ion is a reversed elliptic Wagonspring, possessing great e1ast-ieity, 0f 10W coustruction, thereby allowing the body 0f the vehicle to sit 10W on the axle.

The e1liptie spring now in use possesses advantages over any other shape, givin g greater elasticity; bat in oraler to accornplish this the spring must be made of sufficient stiffness 2md height t0 sustain the load wit;hout co'ming in contact, which wou1d endanger the spring.

In placing springs 011 the ax1es the head is always uppermost. In my reversed elliptic spring the head is also uppermost, as in the 01d spring, reversed, beeanse what; is ordinarily the top'is bent downward 21-nd forms the under spring, and the bottom spring the upper 0ne, describing in its shape the figure eight, (8.) This form Will allowthe two springs to pass one another without coming in contact, avoiding all danger of breakin g by striking together.

In Figure 1, A shows a side elevation 0f the spring. a a are t-he heads. b b are th eyes; c c, the s0lid clips t0 hold the leaf 0 in position. Fig. 2 shows a plzm 0f ohe szune spring.

A sgring thus eonstrueted occupies snmli space, and ha-s great degree of elasticity without dzmger f breaking.

Hzwing thus described my invention, what I claim as new, and desire t0 secnre by Letters Patent, is

A reversed elliptic spring, describing in.its sha-pe 0r contour a triple 100p, the upper and lower secoions baut near the heads a a and eyes b b, sufficient 110 throw then1 0ut 0f verti aal range t0 prewent interfering, substantially as described, rund for the purpose Set. forth.
